The following script will give you the status of your active network interfaces, ie. duplex, speed, auto-negotiation etc. Was taken from a BigAdmin article:

  #!/bin/ksh

  # Simple script to GET stats about network cards
  # Should work on hme and qfe. Will NOT change anything.
  # Will report on speed and config of all network interfaces.
  # Paul Bates 27.03.2000
  # James Council 26.09.2001
  #       - Changed output to one liners.
  #       - Added IPversion check.
  # James Council 10.10.2002 (jamescouncil@yahoo.com)
  #       - Added test for Cassini Gigabit-Ethernet card (ce_).
  #       - Added test for GEM Gigabit-Ethernet (ge_)
  #       - Added test for eri Fast-Ethernet (eri_).
  #       - Added "Ethernet Address" field.
  #       - Removed "IPversion" field.
  #       - Removed checking of a port more than once (i.e. qfe0 qfe0:1)
  # James Council 10.25.2002 (jamescouncil@yahoo.com)
  #       - Fixed 1GB check on ge device.
  # James Council 04.02.2003 (jamescouncil@yahoo.com)
  #       - Added dmfe check (suggested by John W. Rudick, & Erlend Tronsmoen)
  # Octave Orgeron 02.06.2004 (unixconsole@yahoo.com)
  #       - Added bge check (bge_).
  # Octave Orgeron 05.18.2005 (unixconsole@yahoo.com)
  #       - Corrected CE check to use kstat, which is required in Solaris 10.
  # Octave Orgeron 12.13:2005 (unixconsole@yahoo.com)
  #       - Corrected CE and DMFE check. Added IPGE check. Special thanks to
  #         Paul Bates, Christian Jose, and Bill Qualye for suggesting fixes and
  #         for keeping me on my toes;)
  # Octave Orgeorn 02.07.2007 (unixconsole@yahoo.com)
  #       - Added support for the Intel e1000g interfaces.
  #       - Cleaned up script. Housecleaning.
  #       - Tested against Fujitsu Quad GigE Nic's (FJGI)
  # Paul Bates 10.03.2008  (sun@paulbates.org)
  #       - included NXGE interfaces, Thanks Jorg Weiss and Randy Latimer !!
  #       - Just tidied up code a little more, removed some fluff
  #
  # NOTE: For further updates or comments please feel free to contact me via
  #       email.  James Council or Octave Orgeron or Paul Bates
